Lio Min’s Beating Heart Baby is a love letter to internet friendships, anime, and indie rock

When artistic and sensitive Santi arrives at his new high school, everyone in the wildly talented marching band welcomes him with open arms. Everyone except for the prickly, proud musical prodigy Suwa, who doesn’t think Santi has what it takes to be in the band.

But Santi and Suwa share painful pasts, and when they open up to each other, a tentative friendship begins. And soon, that friendship turns into something more. . . .

Will their fresh start rip at the seams as Suwa seeks out a solo spotlight, and both boys come to terms with what it'll take, and what they'll have to let go, to realize their dreams?
